A mother had two sons. One was mentally challenged and another one was normal. Both were playing in a garden.

Another woman came near to her and asked, "Those both are your children?"

"Yes," she said, giving formal smile.

"Who do you love more? Younger one or older one?" woman asked inane question.

"Do you have kidneys?" she asked.

Woman nodded.

"Which one do you love more? Left one or right one?" she said angrily.
